Application September 5, 1947, Serial No. 772,303

My present invention relates to the general class of separable fasteners of the rotating head and socket type, and more specifically to an improved turn button fastener or axial closure adapted for use with wearing apparel and other articles of personal use, as well as for use with luggage, including belts, raincoats, and hand bags.

The primary object of the invention is the provision of a quick detachable or separable safety device of this type that may be manufactured with facility and low cost of production, and in which the parts may be assembled with convenience to constitute a reliable, efiicient, and durable fastener.

The invention consists in certain novel features of construction and combinations and arrangements of a minimum number of parts as will hereinafter be described and more specifically set forth in the appended claims.

In the accompanying drawings I have illustrated a complete example of a physical embodiment of my invention in which the parts are combined and arranged in accord with one mode I have devised for the practical application of the principles of my invention.

It will, however, be understood that changes and alterations are contemplated and may be made in these exemplifying drawings and mechanical structures, as is manifested by the illustrated modifications, within the scope of my claims, without departing from the principles of the invention.

Figure 1 is a face View of a separable fastener in which my invention is physically embodied; and Figure 2 is a central longitudinal detail view of the fastener.

Figure 3 is a central transverse sectional view.

Figure 4 is a face View of the base member or plate of the fastener; and Figure 5 is a face view of the attaching member or plate and turn button or rotary head.

Figure 6 is a perspective view of the body of the turn button with its head omitted for convenience of illustration.

Figure 7 is an under face view of the head of the turn button.

Figure 8 is a plan view of the body of the turn button with the head detached.

Figure 9 is a modified form of the invention showing the attaching plate or member, and the body of the turn button co-acting therewith for attachment to the base plate or member.

Figure 10 is a longitudinal sectional view of the attaching plate and turn button; and Figure 2 Claims. (01. 24-221) 11 is a face view of the base member with its post and cross head.

Figure 12 is a longitudinal sectional view at line I2-l2 of Fig. 11.

Figure 13 is a face view of another form of the invention embodied in a hinged buckle member or plate; and

Figure 14 is a longitudinal detail sectional view of the hinged structure of Fig. 13.

Figure 15 shows a modified form or arrangement of the base member with its post and cross head; Figure 16 is a longitudinal sectional view at line l5-I6 through the belt and adjustable slide or base member; and Figure 1'7 is a transverse sectional view at line I'l--i'l of Fig. 15.

In the preferred form of the invention shown in Figs. 1 through 7, the two adjoining edges E and F may be parts of wearing apparel, or parts of other articles that are to be fastened by the members of the separable fastener of my invention which includes an attaching plate or member l of suitable material, and a base plate or member 2, which plates are fastened as by rivets 3 to the respective parts.

The base plate 2 is cut away to form an open socket or depression 4 having a flat outer face, and a central integral post of the plate is fashioned with a cross head 6 extending longitudinally of the base plate.

A rotary button or turn-button is axially mounted on the post and cross head for fastening the parts, and this structure is carried by the attaching member or plate I. The turn button includes a circular head I that is provided with a pair of holes 8, 8 to receive complementary attaching pins 9, 9 of a tubular body [0 forming a chamber or cylindrical interior bore that merges with and opens into a cross slot H which opens through the inner end of the body.

The attaching plate I is fashioned with a counterbore l2; and the body ll] of the turn button is provided with an exterior annular flange l3, so that the flanged body may be slipped into the counterbore, and then the head I may be fastened on the pins 9, to mount the turn-button for oscillating movement in the counterbored attaching plate or member I.

For fastening the parts the turn button with its cross slot is slipped over the cross head, and then the button is turned through an angle of approximately ninety degrees; the cross head frictionally engages the wall of the chamber Ii], and by cam action of the resilient parts the fastener is held together. For limiting the movement of the turn button, and interlocking the parts, the flange 3 B of the body 12 is provided with a radially extending pin [4 that may travel through a concentric arcu-ate guide groove l5 of the attaching plate I.

In Figs. 9 through 12 a modified form of the invention is shown wherein the attaching plate I6 is coupled to a belt end G, and the base member is attached to the end H of the belt. This base member includes a circular disk I! and a complementary disk I'8 secured by rivets [9 on the end H, andthe'post 5 with its cross head 6 is rigid with the outer disk I8.

The attaching plate I6 is fashioned with "a truncated V-shape groove 20, and the flange l3 of the turn button is provided with a complementary V-slot [9 that are adapted to'register, in order that the attachment maybe made'by a longitudinal movement of the attaching plate whereby the V-slots guide the turn button-into engagement with the post, and then the button may be turned to -lock the parts together.

Figures 13 and 14 show an adaptati-on of the invention-toafastener for asuit case or similar article of luggage in which the turn button is combined with wan attaching plate 2| that is hinged at-Zltosa hinge plate-23 riveted to a part 24 of the suit case, and the turn button coacts With the complementarybase member of the separable fastener.

In'Figures 15, 16, 1'7 aportion of a leather'belt isshown at-25 andsprovided with the usual perfo'rations .26, and'a slidable base member 27is adiustably mounted on-the belt, and provided with corner clips 28 for guiding and retaining the member in adjusted position. A'pin 29, which is provided with across head 30 is mounted in the slide 27 andadapted to bepassed through as elected one of the perforations 26, and the turn button is adapted for engagement with the cross head and pin.

Having thus fully described my invention, What movable within the extent of said arcuate groove and engaging the end walls thereof to limit the movement of said turn button, and said body having 'an interior chamber merging with a cross slot engagin'g the-cross head through longitudinal movement of said base plate.

2. In a separable fastener, the combination with a base plate having a post and an integral cross head, of an attaching plate having a countersunk bore and a truncate'd V-shape slot leading from the countersunk bore to the edge of the'attaohingplate, or a turn button hav'inga reduced body and an annular exterior fiange, said flange having a V-shape slot registering with the truncated slot, and saidbody having-an interior chamber merging with a cross slot engagin'g the post and cross head.
